Part 2 - Final Exam Review

1. Magnetic fields can be seen with your eyes when

• you rub your foot on the carpet
• atoms have an equal number of protons and electrons
• iron filings are placed over a magnet
• all the electrons are spinning in the same direction

2. Tell what would happen if these two magnets were lined up like so?

• They would Attract
• They would Repel

3. What do the field lines tell us about the electric or magnetic force?

• what they are acting on
• how strong the force is
• how far apart the forces are
• where to find the pot of gold

4. Which of the following images would NOT create a stronger magnetic force?

• 
• 
• 
• 

5. The graph below shows the magnitude (strength) of the magnetic force at various distances. What can be said about the data shown below?

• As distance increases, the magnetic force decreases
• As force increases, distance increases
• As distance decreases, force decreases
• There is no correlation/relationship between force and distance

6. Which pair of magnets will demonstrate attraction

• Pair 1 & 2
• Pair 3 & 4
• Pair 1 & 4
• Pair 2 & 3

7. This magnetic field is an example of...

• Attractive magnetic force
• Repulsive magnetic force
• No magnetic force
• All of the above

8. The Earth has a magnetic field that protects us from deadly ___

• Aliens
• Solar Radiation
• Meteors

9. The picture below shows an interesting game, where you use magnetic "donuts" to create a pattern. Some of the donuts stack directly on top of each other and some have a space between them. WHY is there a space between the magnets?

• They are attracting (North pole facing North pole)
• They are repelling (south pole facing north pole)
• They are repelling (south pole facing south pole)
• The charge is neutral

10. The picture below shows how the atoms in this mystery object are flowing. This object is...

• Magnetic
• Non-magnetic
